I am certain a resident FR scientist or crowd controller will be more than willing to set me straight on this, but, do we have records of anomalies that may have preceded catastrophic North American events that haven’t happened in a very long time and may happen again some day?
Well the biggest pre-quake catastrophe research has to do with the ionosphere anomalies. Japan and Haiti both had very strong signals a few days before their quakes however I know of know correlation between these type of booms and impending doom.
Supposed recording seismically of the booms.
